BAFFLE :WAIJL :TOOL.

Application filed April 9, 1926. Serial n 16 9 7855.

This invention is a special tool for use in building or repairing thebaflle walls of water tube boilers, where such walls are composed of orinclude outer shells of blocks or tiles which overlap one another fromtop to bottom, as described in my separate application for patentcovering a special form of such tile. V

' The object of this invention is to provide a tool by the use of whichthe form of tiled baffle walls referred to may be readily constructed inwater tube boilers.

In the drawing Fig. 1 is a perspective view, showing the tool in use inconstructing a tiledbaflle wall;

Figure 2 is a view of the tool, holding the special form of tile forwhich it is designed;

. Figure 3 is a. view of the said special form of tile. apart from thetool;

Figure l is a front elevation of the tool alone; t

Figure 5 is a rear elevation of the tool;

Figure 6 is an edge view of the tool.

This invention is a tool for use in connection with the form of baffletile illus trated at 1, and which is flat, having the paralleloppositely disposed beveled ends 2 tapering from the opposite faces ofthe tile as shown at 3, and the intermediate arcuate cut-outs 4 whichare adapted to laterally engage two adjacent water tubes 5 as mounted ina water boiler (not shown).

This tool comprises a tile holder 6 of sheet metal, the holder beingformed of an arcuate or bow-like shape in the plane of the sheet ofmetal, as shown in Figures 4 and 5. One end of this holder is bentslightly out of the said plane, as shown at 7 so as to conform to eitherofthe beveled ends 2 of the tile 1, when the tile is properly positionedupon the tool. The parallel extremities of the holder are then bent outsubstantially perpendicularly to the body of the holder, to form flanges8. to which are secured tile clamps 11 made of strips of relatively thinspring metal, and which are adapted to resiliently engage the straightparallel edges of the ends 2 of the tile when the same is placed in theholder. A working handle 9 is hinged at 10 to the back of the holder 6.the hinge 10 being set askew as shown, with reference to the medial oraxial line connecting the flanged ends of the holder, in order tofacilitate the operation of the tool in the slightly out of its plane,the said holder manner now to be described.

In the use of-this tool, a tile lis positioned upon the tool, as shownin Figure 2 where it is releasably held by the spring clamps 11. Thehandle 9 is then turned flat against the back of the holder, and theholder carrying the tile is then inserted obliquely up through one ofthe alleys between the rows of tubes. laterally adjacent tubes, as5, arereached, transversely between which it is desired to When the two locatethe tile, one of the arcuate ends of the tile is positioned against oneof the tubes. Then by manipulation of the handle 9 and drawing'same outfrom the back of the holder and at the same time keeping the horns ofthe 'arcuate end of the tile first placed in engagement with the tube,astraddle of that tube, the opposite arcuate end of the tile is causedto rise and the tile to assume a transverse horizontal position 'betweenthe two tubes 5, with the two arcuate ends 4: of the tile in lateralengagement with the two tubes 5. The process is repeated .Wltlladditional tiles until the wall or shell is completed, the tiles beinglocated in a common plane and in overlapped relation, as explained in myseparate application covering the subject matter of the said tile.l/Vhile I have hereindescribed a certain specific manner and method ofconstructing and assembling the elements of my invention, it isunderstood that I may vary from the same in minor details, not departingfrom the spirit of my invention. so as best to construct a practicaldevice for the purpose intended, as defined in the appended claims.

I claim;

1. A tool of the kind described, comprising a flat tile holder havingtwo opposite ends thereof made parallel; resilient tile clamps fixed atthe said two opposite ends of the holder for releasably engaging a tile;

and a handle hinged at the, back of holder.

2. A tool of the kind described, comprising a flat tile holder, arcuate'in the plane of the holder, two opposite ends thereof being parallel;resilient tile clamps fixed at the said two opposite ends of the holderfor releasably engaging a tile; and a handle hinged at the back of theholder.

3. A tool holder of the kind described, comprising a flat tile holderarcuate in its own plane and having an end thereof bent the a;handle'hingedeskew atthe back of the V "holder. 7 V

4. In combination with a bafiie tileof the kinddescribed, a 001 of thekind described, comprising a fiat 'tile'holder arcuatein its i own'plane and having an end thereof bent slightly out of its plane, thesaid holder having two oppositeparallel extremities; means at the saidtwo opposite ends of the holder for' releasablyr-engaging a tile; and ahandle hinged askew at the back of the ho1der.'- r

In testimony whereof I affix my signature.

JOHN A. MACDOWELL.
